HVC 4223F

Flex Servo-Drive for Direct Control of Electric Motors (Stepper / BLDC / BDC)

Short Description

The new HVC 4223F flex servo-drive from Micronas enables cost-effective realization of high-performance compact electric motor control. Powered by a 32-bit CPU core (ARM Cortex-M3), the HVC 4223F economically addresses growing challenges in the automotive market and beyond (industrial, consumer, instrumentation, etc.). The flexible peripherals of the product provide all means to directly control brush-type, stepper (bipolar or three phase), or brushless (BLDC) motors directly via the integrated high-performance half-bridges without the need for external drivers.


Beside timers/counters, interrupt controller, multichannel ADC, SPI, and enhanced PWMs with diagnosis functions, this device contains an advanced LIN UART with a LIN 2.x transceiver, as well as voltage regulators to connect the device directly to a 5.4 V…18 V Automotive board net. Various power management modes optimize current consumption. The HVC 4223F further features a flash program memory with a size of 32 kbytes, providing high flexibility in code development, production ramp-up, and in-system firmware update.


Various integrated digital and analog circuit units such as comparators with virtual star point reference, current scaling and an embedded programmable gain amplifier allow users to minimize the number of external components. The computation capacity supports complex motor control algorithms such as Space Vector Modulation (SVM) for permanent magnet synchronous motors (PMSM) in addition to six-step commutation with sensor feedback or sensorless control, as well as various stepper configurations.
